Almighty Sunburst

As you prepare for the spell, the gemstone in front of you floats just above your hands, which are shaped like a bowl.

The gem splinters until it finally shatters, releasing a miniature of a star that, except for the user, burns all creatures and vegetation within 36 m/120 feet with flaming solar storms. All creatures within these 36 m/120 feet must make a Dexterity Saving Throw.

On a failed save, that creature suffers 10 D12 (60) Radiant damage and 5 D12 (30) Fire damage and half as much on a success.

As an bonusaction, you can push the mini-star in a certain direction to focus the solar storms, which ends the spell afterwards. The focused beam measures 30 cm/1 feet in diameter and leaves an equally wide hole in everything and everyone. Creatures that get hit by it must make a Dexterity Saving Trow.

On a failed save, that creature suffers 40 D12 (360) Radiant damage and 15 D12 (90) Fire damage.

On a successful save, that creature suffers 20 D12 (240) Radiant damage and 10 D12 (60) Fire damage.
